As an NT Administrator I have read many Linux books trying to bridge my NT knowledge to the Linux and Unix world, this book is by far the best.
Most of the Linux books I have read before tell you what to do to administer a Linux server, but they assume that you know how to do it. Gerhard Mourani tells you in detail what to do, how to do it, and why to do it. I have learned a great deal not only about Linux server applications, but about the Linux operating system itself.
If you want to take advantage of Linux's versatility as a server operating system, and do it in the most secure and efficient manner, you can find no better book than this one. In addition to operating system configuration there are many chapters individually dedicated to installing and configuring specific Linux server applications such as Sendmail, SQL server, Apache, BIND, and many more.
One disclaimer: If you are looking for information on how to build a Linux workstation or cool Gnome desktop, this is not the book for you. It is focus is exclusively building Linux application servers.
